How Melissa McCarthy Left Guests at Adam Levine's Halloween Party 'Horrified'

— -- Melissa McCarthy really liked living next to Maroon 5 frontman Adam Levine.

Though she admitted that she sometimes got "goofy" when she'd catch a glimpse of him, the biggest perk may have been the invite she once scored to his big Halloween party.

"I'm pretty sure we got a pity invite just so we wouldn't call the cops," she told Jimmy Kimmel during an appearance on "Jimmy Kimmel Live." "I was not [usually] hanging out with Adam Levine."

So, it's understandable that her costume -- she came dressed as her goofy Midwestern aunt -- didn't exactly blend with those of his female friends. Those women, she said, were all clad in bikinis, and didn't entirely understand why she came dressed as she did.

"They were like, 'Why did you do that?!'" McCarthy, now starring in the film "St. Vincent," recalled. "They were so horrified that I looked like that! [To them], it wasn't funny. It didn't seem ironic."
